lMPROVEMENT lN R-EVOLVI NG FIRE-ARMS.

Specification forming part of Letters Patent No. 99,893, dated February15, 18 70.

To all whom it may concern:

Be it known that LBYRON R. HILL, of Granston, in the county ofProvidence and State of Rhode Island, have invented a new and ImprovedRevolver-Cylinder; and I do.hereh,,v declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being bad to theaccompanying .same may be placed with either end against the stock, sothat. they can be fired from either end.

The invention consists in the arrangement of conical apertures throughsuch cylinder, which are so distributed that the cylinder may at oncecontain two sets of cartridges,.oue set' being put iufrom either end.

A in the drawings represents the rotating cylinder ofarevolving fire-armof suitable kind.

B O are two notched or ratchet wheels formed on'the opposite ends of thecylinder, respectively, and concentrically around the central bore, a,of the same. Their teeth stand in opposite directions, so that thecylinder will turn alike when reversed. This cylinder may, as in Fig. 4,have the ordinary kind of cylindrical apertures, b b, forreceiving thecharges. These apertures, however, have enlargements or When thecartridges are inserted from one end, so that their heads or flanges mayrest-in the chambers c, the cylinder is inserted with the wheel B towardthe firing and revolving mechanism. When all the charges havebeen-exploded the next set of cartridges is put in from the oppositeend, so that their flanges rest iu-the chambers d. The cartridges thusput in from the opposite side push out the shells of those, formerlyexploded. Thus the separate act of pushing out the old cartridge-shellsby the rumrod is dispensed with, as the alternateloading from oppositeends serves the same purpose. Much time in loading is thus saved.

In Figs.'1, 2, and 3 is represented a cylinder having conical apertures0 eff for the reception of the charges. The apertures c e' have theirlarger ends on the same end of the cylinder on which the wheel (J isarranged, while the apertures f are larger in line with the wheel B. Theapertures of are arranged in a circle around the axis of the cylinder,but in alternate succession, as is clearly shown in Fig, 2. By thisconical form of apertures much space is economized, and a larger numberof cartridges may be secured in one cylinder. The cylinder may at oncebe loaded from both ends. The cartridges in c are exploded when E is incontact with the working mechanism. When they are all discharged thecylinder is reversed, sothatGcomesiuto gear. Then the cartridges infareexploded. shaped to correspond with the apertures ef, and have theirfulminates at the small ends.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The conical apei tures cf, arranged in reverse orderin alternate succession in the cylinder" of a revolving fire-arm, as setforth.
